Mechanical motors for spring-driven toys give some diflicnlty aste themeans of locking the spring as it is Wound.l `Where a springactuatedpawl is used-a spring of suftion oi the parti gives 'such engagement tothe .pawl against reverse movement that the through a reverse `windingoi' the spring. The present invention contemplates the use et a paivlhaving thas reducing any resistance to the turning oit .the ratchetwheel with reverse Winding through the over-running of the toy; or therunning of the toy by the user. In. this Way the breakage oit springs isvery mach reduced. Further such a porvi-can be Aconveniently mounted in`the device and `vthe absence of necessity for a spring cheapens themountingan important feature in devices of .this hind. Other :features.and de- 'ra-iis or' the invention will appear from the specificationand claims.

The invention is illustrated in the accomf ipanying drawings as followsFig. l shows a sideelevation ot a toy including #mechanical-motor, apartei the broken away to show .construction.
